I'm having a problem with my setup. First off, I have my 360 and ps3 hooked up to the receiver via two HDMI, then one HDMI-out to my TV. Ive found (on my 360 at least) that during games, if the action gets heavy the audio will cut out for a split second, usually a couple times in quick succession. I looked at the receiver when this happened and the Dolby Digital symbol disappears each time the audio drops. Games in question, Dead Space 2 and Dead Rising 2: Case West, both for Xbox 360.
It's really frustrating and I'd really appreciate anyone's help.
